Daerah penelitian secara administratif berada di Kecamatan Sangatta Utara,
Kabupaten Kutai Timur, Provinsi Kalimantan Timur. Area penelitian merupakan
wilayah izin usaha pertambangan PT. Kaltim Prima Coal. Kegiatan penelitian
dilakukan pada wilayah penambangan batubara dengan sistem penambangan terbuka.
Penelitian ini memiliki area dengan persebaran Geological Strength Index (GSI) dan
Uniaxial Compressive Strength (UCS) yang berbeda, terletak di pit tidak aktif dan
akan di aktifkan kembali sehingga perlu adanya kajian kondisi geologi dan geologi
teknik. Metodologi yang digunakan pada penelitian ini meliputi pengambilan data
permukaan di lapangan dengan melakukan pemetaan geologi dan geologi teknik.
Selanjutnya, melakukan analisis laboratorium dari data lapangan dan analisis data
sekunder. Analisis data sekunder geologi teknik yaitu persebaran beserta pemodelan
zonasi rawan longsor berdasarkan nilai Geological Strength Index (GSI) dan Uniaxial
Compressive Strength (UCS). Analisis data lapangan dilakukan dengan metode
scanline untuk mendapatkan parameter massa batuan. Berdasarkan aspek
geomorfologi daerah penelitian dibagi menjadi dua bentukasal dan enam
bentuklahan yaitu area bukaan tambang (A1), disposal (A2), kolam pengendapan
(A3), kolam tambang (A4), perbukitan terkikis (D1), dan bukit sisa (D2). Stratigrafi
penyusun daerah penelitian yaitu Satuan disposal, Satuan batupasir Balikpapan,
dan Satuan batulempung Balikpapan dengan struktur geologi sesar naik, kekar
gerus, dan cleat. Pada aspek geologi teknik memberikan pemodelan rekomendasi
geologi teknik terkait nilai persebaran Uniaxial Compressive Strength (UCS)
dengan rentang nilai 1,12 – 2,22 dan Geological Strength Index (GSI) dengan
rentang nilai 53,7-62,2. Zonasi rawan longsor dibuktikan pada sayatan A-A’ yang
menghasilkan nilai faktor keamanan 0,994 (lereng kritis) dan pada sayatan B-B’
yang menghasilkan nilai faktor keamanan 1.345 (lereng stabil).
Kata kunci : Geologi, GSI, Pemodelan, RMR, UCS.

The research area is administratively located in North Sangatta District, East Kutai
Regency, East Kalimantan Province. The research area is the mining business license
area of PT Kaltim Prima Coal. The research activities were conducted in a coal mining
area with an open pit mining system. This research has an area with different Geological
Strength Index (GSI) and Uniaxial Compressive Strength (UCS) distribution, located in
an inactive pit and will be reactivated so that it is necessary to study geological conditions
and geological engineering. The methodology used in this research includes collecting
surface data in the field by conducting geological mapping and engineering geology.
Furthermore, conduct laboratory analysis of field data and secondary data analysis.
Secondary data analysis of engineering geology is the distribution and modeling of
landslide-prone zonation based on Geological Strength Index (GSI) and Uniaxial
Compressive Strength (UCS) values. Field data analysis is a scanline to obtain Rock
Mass Rating (RMR). Based on geomorphological aspects, the study area is divided into
two landforms and categorized as six landforms, namely mine opening area (A1),
disposal (A2), settling pond (A3), sump (A4), eroded hills (D1), and residual hills (D2).
The stratigraphy of the study area is Balikpapan sandstone Unit and Balikpapan
mudstone Unit with the geological structure of thrust faults, shear joints, and cleats. The
geological engineering aspect provides recommendation modeling related to the
distribution value of Uniaxial Compressive Strength (UCS) with a value range of 1.12 -
2.22 and Geological Strength Index (GSI) with a value range of 53.7-62.2. Landslide
prone zonation is evidenced in the A-A' section which produces a safety factor value of
0.994 (critical slope) and in the B-B' section which produces a safety factor value of
1.345 (stable slope).
Keywords: geology, GSI, modeling, RMR, UCS.
